Abstract

The invention discloses an underwater rapid flange connector. The underwater rapid flange connector comprises a guide barrel assembly, a compressing cylinder, a subsea pipeline, hinge pins and a distance increasing cylinder, wherein the guide barrel assembly is arranged on the surface of the subsea pipeline, and a half slip of a guide barrel is arranged at the outer part of the guide barrel assembly, and the guide barrel assembly comprises two half slips of the guide barrels; a guide barrel rotating hinge is arranged on the surface of each half slip of the guide barrel; the hinge pins are arranged in the guide barrel rotating hinges; the hinge pins are fixedly connected to the guide barrel rotating hinges through limiting clamping plates; and a guide barrel body is arranged in each guide barrel rotating hinge. The underwater rapid flange connector is simple in structure, reasonable in arrangement, safe, practical, and simple and convenient to operate; the difficulty in underwater flange connection, particularly connection of high-pipe-diameter flanges and high-pound subsea pipeline flanges, can be greatly reduced, and the adverse sea condition factor influences such as high flow speed, complex underground condition, low visibility, frequency cold air in winter of sea areas in west of South China Sea can be reduced.

Description

technical field

[0001] The invention relates to the technical field of flange connectors, in particular to an underwater flange quick connector. Background technique

[0002] When laying sea pipes in offshore oil engineering projects, the connection between the sea pipe and the riser needs to use flanges for underwater connection. Due to the frequent impact of cold air and other problems, the time to meet underwater diving operations is very limited; in addition, when the flanges of large-diameter and high-weight sea pipes are connected by traditional bolts, they lack efficient centering and fastening tools, making underwater operations difficult Very big. Therefore, it is difficult to install and connect with traditional flange bolts when laying and connecting submarine pipelines, the operation time is long, the construction period cannot be guaranteed, and the overall cost is high.

[0003] In the process of laying and connecting the sea pipes, the traditional bolt conne...
